Fifteen years and going strong!
There should be a + and - checkbox for the Transpose Window. So you can -instantly- go from +12 semitones to -12 semitones. I screw with this -every- day. (Octaves are a big deal in orchestration. HELLO!)
There should be -presets-. Like ‘Up a fifth’ and ‘Down a fourth’ and ‘Parallel Sixths–in key’.
And don’t get me started on how there SHOULD be a default key (ie. hitting [Enter] is the same as clicking ‘OK’.
These are the kinds of things that -I- need.
